.To aZZ whom it may concern:

ie itknown thatwc, \VILLt.-\3I IL AKINS and J osnrn (l. Umtnt'r'r, of Ithasa, Tompkins county, New York, have invented certa-in new and uset'ul Improvements in Galclnlar-U10cks; and that on the, 19th day of September, 1554, we did obtain Letters Patent; for the same, which Letters 'Patent'wcrc extended to usit'or the period ot'scvcn vears fro-1n tl1ejnst.-named date, on the 15th dav ot' September, ISGS; and

owing.:v to delicieJn-.ies` in our title, speeiiieai tion, and claims, or certain portions ot', these, which we believe have occurred through inadrerteney, mistake, or other errors, and not. h v an y fraudulent intent, we have surrendered the said extended Letters latent and have f requested new reissued Letters Patent in their place: Kou', therefore, we do declare that the t'ollowingis a i'ull and accurate description of our invention, reference being had tothe accompanging drawings, and to the letters:

would raise the plate 44 high enough t'or click 4l, movingl cylinder l, to drop over the next tooth above the one. on which it'l stood. v liefore being raised, the hent end of the arm ot' plate 1L having raised the detent 23 alittle above the teeth -ot' 'the wheel 45, Fig. (l, the rod 3() running loosely through the end ot lever Y, and secured from falling' ont hy a hook or nut at the top of it, would at the same time raise plate elhigh .enough for click 37 to pass over t'onr teeth on the wheel L, the arm or pin 55 on the. side ot' rnd 30 lifting.: the decent X a littleahove the teeth of wheel L at twelve oclock at midnight, the clicks being' eazried into their places hy weights 'or springs. 'lhe helix or cani V having,r moved Vorn-ard enough to let the lever Y drop t'roni its outer end, the springs 5 and S, 'drawing down the clicks :t1 and lli', tarning cylinder F and wheel L, the detents-X l and 2:3, heilig drawn between the teeth ot' their respective wheels hy the springs- 42 and U, stopping cylinder 1 and wheel L at'ter being moved one tooth each, the cylinder F will showMonday,and the hand .l the second day ot the month. r[he same ehane'es'of the days ot' the. week and ot' the days olthe monili will vhe produced at every succeeding; twelve ocloeli ai, midnight. And as the wheel L I revolves, Vthe cam 2 on its shaftraises lever 16, which operates on roller G and wheel M i in the saine way, and hy means of similar machine1' v,`ns lever l' operates on cylinder Fand wheel Il in the precedingoperation, ,thus movine' lthe roller (i from January -to lfelnnary, as wheel l. moved the hand l to the iirst day ot' the succeeding,r month, Att'he same time the wheel .ll, wilh cam X attached, is moved t'or- 1 ward one forty-eigrhth ot'a revolution, raies-ingr 'i the arm (.lI on the. top ol' the next ray ot" the I plateor cam N, Flexi, removing' thcdetent X* in the wheel li, l"i ;'.,marlaalashavingtwentyeight-teeth, it having.;` stood on theone having'.

thirty-one teeth dln-ine' the preceding month of January, the month -ot February having only twenty-eight, and the plate X will turn one ray. t'orward at the lirst lay ot' each month. moving; the detenta X hacha-ard .and forward on the. face ot' the wheel L hy means` Q ot' the rocking shatt l, and arm t) and (@so A mouth t'or four years, in which time the. plate A N peril-irais one revolution. Y

'.lhe. roller (l. with helix 4f? attached, being movediinward monthly as in the'preeeding operation, would consequently malte one revolution ln eaeh year, the cam li raising the A click 3S -hy the intervening; machinery, as slunvn in ideali, the. cam heing so placed on ltheqvlinder (i as that the lever 22 will drop lroni the outer end ol the earn, as the cylinder tnrnsl'rom leeeniher to January, thus allowine' the machinery tu turn the cylinder ll so as to show 1555 at the same moment the other changes are heine; made, every change being made at precisely twelve ocioek at night.
